Choosing your season on the northern circuit

There is no single best month for a Tanzania safari — there is a best month for the safari you have in mind. Rainfall, grass height, herd movement and how busy the parks feel all move together through the year.

The long dry season: June to October

Grass is short, water is concentrated and animals gather around rivers and waterholes, which makes game viewing consistent and predictable. The Serengeti also holds the northern herds in these months, and the Mara River crossings usually fall between July and September, though the exact timing follows the rain and never a calendar.

This is the busiest period in the parks and in the crater, so lodges and camps are booked far ahead. If your dates fall here, the routing matters more than usual: we stagger crater descents and game drive starts so your days do not run with the crowd.

The short rains: November and December

Brief afternoon showers, dramatic skies and green plains. Wildlife spreads out a little, but the parks are quieter, photographic light is at its best and rates soften before the festive weeks. Tarangire and Lake Manyara are especially rewarding at this time.

The green season: January to March

The southern Serengeti and Ndutu area hold the herds for calving, which draws predators and produces some of the most concentrated wildlife action of the year. Roads can be soft after rain, so a private vehicle and an experienced guide make a real difference.

The long rains: April and May

The wettest stretch, with some camps closed and some tracks difficult. It is also the quietest and the best value, and for travellers who do not mind rain the landscapes are at their most beautiful.

Pairing safari with Kilimanjaro or Zanzibar

Kilimanjaro climbs are most reliable in the same dry windows — January to mid-March and June to October — so a climb and a safari sit naturally in one trip. Zanzibar works nearly year round, with the long rains being the main exception.
